To determine the correct formula for the compound formed from element W (which has 2 valence electrons) and element X (which has 7 valence electrons), we can analyze their charges.
Element W, which has 2 valence electrons, will likely lose those electrons to form a cation with a charge of +2 (W²⁺).
Element X, on the other hand, has 7 valence electrons and can gain 1 electron to form an anion with a charge of -1 (X⁻).
To balance the charges in the compound formed by W and X:
- One W²⁺ ion will balance with two X⁻ ions, since +2 from W will balance -1 from each X (2 x -1 = -2).
Thus, the correct formula that represents the compound formed by elements W and X is \( WX_2 \).
Therefore, the answer is: **WX2**.
